Definitions

  • the present invention relates to hydrocarbon fluids and their uses.
  • Hydrocarbon fluids find widespread use as solvents such as in adhesives, cleaning fluids, solvents for decorative coatings and printing inks, light oils for use in applications such as metalworking and drilling fluids.
  • the hydrocarbon fluids can also be used as extender oils in systems such as silicone sealants and as viscosity depressants in plasticised polyvinyl chloride formulations.
  • Hydrocarbon fluids may also be used as solvents in a wide variety of other applications such as chemical reactions.
  • hydrocarbon fluids vary considerably according to the use to which the fluid is to be put.
  • Important properties of hydrocarbon fluids are the distillation range generally determined by ASTM D-86 or the ASTM D-1160 vacuum distillation technique for heavier materials, flash point, density, Aniline Point as determined by ASTM D-611 , aromatic content, viscosity, colour and refractive index.
  • Fluids are can be classified as paraffinic such as the Norpar® materials marketed by ExxonMobil chemical Company, isoparaffinic such as the Isopar® materials marketed by ExxonMobil Chemical Company; dearomatised fluids such as the Exxsol® materials, marketed by ExxonMobil Chemical Company; naphthenic materials such as the Nappar® materials marketed by ExxonMobil Chemical Company; non-dearomatised materials such as the Varsol® materials marketed by ExxonMobil Chemical Company and the aromatic fluids such as the Solvesso® products marketed by ExxonMobil Chemical Company.
  • paraffinic such as the Norpar® materials marketed by ExxonMobil chemical Company
  • isoparaffinic such as the Isopar® materials marketed by ExxonMobil Chemical Company
  • dearomatised fluids such as the Exxsol® materials, marketed by ExxonMobil Chemical Company
  • naphthenic materials such as the Nappar® materials marketed
  • hydrocarbon fluids are derived from the refining of refinery streams in which the fluid having the desired properties is obtained by subjecting the most appropriate feed stream to fractionation and purification.
  • the purification typically consists of hydrodesulphurisation and/or hydrogenation to reduce the sulphur content or, in some instances, eliminate the presence of sulphur and to reduce or eliminate aromatics and unsaturates.
  • the aliphatic hydrocarbon fluids are produced from virgin or hydro-skimmed refinery petroleum cuts which are deeply hydrodesulphurised and fractionated. If a dearomatised fluid is required the product that has been deeply hydrodesulphurised and fractionated may be hydrogenated to saturate any aromatics that are present. Hydrogenation can also occur prior to the final fractionation.
  • the boiling range of hydrocarbon fluids is measured using the atmospheric boiling measurement technique ASTM D-86 or its equivalent.
  • ASTM D-86 is typically used to measure boiling temperature up to around 370°C, more typically up to 360°C. If however the fluid contains a fraction boiling above 365°C it may be more convenient to use the ASTM D- 1160 technique which measures the distillation temperature using vacuum techniques.
  • ASTM D-1160 the boiling range of a fluid having a final boiling point above 365°C may be measured by ASTM D-1160.
  • the fluids of the present invention have a variety of uses in for example drilling fluids, industrial solvents, in printing inks and as metal working fluids.
  • the fluids are however particularly useful as components in silicone sealant formulations where they act as extender oils.
  • Hydrocarbon fluids have been proposed as extenders in silicone sealant formulations as is shown in United States Patent 5863976 which uses predominately hydrocarbons and European Patent Application 885921 - A which uses a fluid that is predominantly paraffinic.
  • European Patent 842974 - B uses fluids based on alkyl cyclohexanes.
  • the hydrocarbon fluids are included in order to provide the formulation with the desired characteristics and also because they are cheaper than the non-reactive silicone oils which are used as the conventional extenders in silicone sealant formulations. .
  • the present invention therefore provides hydrocarbon fluids having ASTM D-86 boiling point ranges within 235°C to 400°C and containing more than 60 wt % naphthenics and at least 20 wt % of polycyclic naphthenics.
  • the fluid contains more than 70 wt % naphthenics. It is also preferred that the fluid have an aniline point below 100°C. A yet further preferred embodiment is that the fluid have an aromatics content below 2 wt %, more preferably below 1 wt %.
  • the invention provides the use of a hydrocarbon fluid having ASTM D-86 boiling point ranges within 235°C to 400°C and containing more than 60 wt % naphthenics and at least 20 wt % of polycyclic naphthenics as a silicone extender oil.
  • the invention provides a silicone sealing composition
  • a silicone sealing composition comprising from 30 to 60 wt % of a silicone polymer and from 10 to 40 wt % of a hydrocarbon fluid having ASTM D-86 boiling point ranges within 235°C to 400°C and containing more than 60 wt % naphthenics wherein at least 20 wt % of the naphthenics are polycyclic materials.
  • An ASTM D-86 boiling point range of 300°C to 370°C is preferred for silicone extenders because it gives a good balance between compatibility and volatility particularly at higher addition levels.
  • the invention provides the use of a hydrocarbon fluid having ASTM D-86 boiling point ranges within 235°C to 400°C and containing more than 60% naphthenics at least 20 wt % of the naphthenics being polycyclic materials as a solvent for a printing ink. If the boiling point range extends above 370°C it may be preferred to use the ASTM D-1160 measurement technique.
  • the invention provides an ink comprising a pigment and a resin and, as a solvent, a hydrocarbon fluid having ASTM D-86 boiling point ranges within 235°C to 400°C and containing more than 60 wt % naphthenics wherein at least 20 wt % of the naphthenics are polycyclic materials. If the boiling point range extends above 370°C it may be preferred to use the ASTM D-1160 measurement technique.
  • the material used with the silicone sealant or in the inks contain more than 70 wt % naphthenics, has an aniline point below 100°C and an aromatic content below 2 wt % more preferably below 1 wt %.
  • hydrocarbon fluids of the present invention have an ASTM D-86 boiling range no greater than 75°C, preferably no greater than 65°C, more preferably no greater than 50°C.
  • Naphthenics are cyclic saturated hydrocarbons and the method used for determination of naphthenic content of the hydrocarbon fluid is based on ASTM D-2786: "Standard test method for hydrocarbon types analysis of gas-oil saturates fractions by high ionising voltage mass spectrometry".
  • This method covers the determination by high ionising voltage mass spectrometry of seven saturated hydrocarbon types and one aromatic type in saturated petroleum fractions having average carbon numbers 16 through 32.
  • the saturate types include alkanes (no rings), single ring naphthenes and five fused naphthene types with 2, 3, 4, 5 and 6 rings.
  • the non-saturated type is monoaromatic.
  • the samples must be non-olefinic and must contain less than 5 volume % monoaromatics. This is mostly the case for product samples.
  • aromatics are separated and determined by Liquid Chromatography or by Solid Phase Extraction.
  • the normal paraffins are separated and determined by Gas Chromatography upstream of the mass spectrometer. It is preferred to have a normal paraffin content below 10 wt %.
  • the relative amounts of alkanes (no ring), 1-ring, 2-ring, 3-ring, 4-ring, 5-ring and 6-ring naphthenics is determined by a summation of mass fragment groups most characteristic of each molecular type. Calculations are carried out by the use of inverted matrices that are specific for any average carbon number.
  • the fluids of the present invention contain at least 20 wt %, preferably at least 30 wt % more preferably at least 45 wt % of 2-ring, 3-ring, 4-ring, 5-ring and 6-ring naphthenics. From the relative amount of alkanes, the amount of iso paraffins can be determined by deducting the amount of normal paraffins from the amount of total alkanes.
  • the aromatics content of the fluids is measured by ultra violet absorption.
  • the fluids of the present invention may be obtained by the hydrocracking of refinery streams and fractionating the hydrocracked product to obtain a cut having the desired boiling characteristics and then hydrogenating the desired cut to saturate the aromatics.
  • Hydrocracking is a process that is used in refineries to convert heavy crude oil cuts into lighter and upgraded material. In hydrocracking the heavy molecules are cracked on specific catalysts under high hydrogen partial vapour pressure. Hydrocracking is traditionally used on vacuum gas oil or vacuum distilled fractions from reduced crude oil which is the residue left after atmospheric distillation. Typically this material corresponds to crude cut points between 340°C and 600°C and boils in the range 200°C to 650°C as measured by ASTM D-1160.
  • hydrocracking processes may be found in Hydrocarbon Processing of November 1996 pages 124 to 128.
  • hydrocracker units have been used to crack heavy crude oil cuts or vacuum distilled crude oil cuts to produce upgrade materials such as kerosene, automotive diesel fuel, lubricating oil base stock or steam cracker feed, however hydrocrackers have not been used to produce feeds for the production of hydrocarbon fluids.
  • Examples of hydrocracking and its use may be found in United States Patent 4347124, PCT Publication WO 99/47626 and United States Patent 4447315, these documents are not however concerned with hydrocarbon fluids.
  • a typical feed to hydrocracking to produce the fluids of the present invention has the following properties:
  • Aromatics from 40 to 65 (1) wt %: 1 ring from 13 to 27, 2 ring from 10 to 20, 3 ring from 7 to 1 1 , 4 ring from 6 to 12, total
  • the sulphur level (in wt % range) is measured by ASTM D-2622 using X-Ray Fluorescence.
  • the product of hydrocracking may then be fractionated and hydrogenated to produce the highly naphthenic fluids of the present invention.
  • the subsequent processing of hydrocracked vacuum gas oil cuts may include, hydrogenation to reduce the level of aromatics and fractionation to obtain a fluid of the desired composition and ASTM D-86 boiling characteristics. We prefer that, when both hydrogenation and fractionation are involved, fractionation takes place before hydrogenation.
  • the fluids that according to the present invention have a boiling range from 235°C to 400°C as measured by ASTM D-86 or equivalent, ASTM D-1160 may be used if the Final Boiling Point is above 365°C. That is to say that both the Initial Boiling Point and the Final Boiling Point are within the range of 235°C to 400°C.
  • the boiling range be no greater than 75°C and preferably no more than 65°C, more preferably no more than 50°C; the boiling range being the difference between the Final Boiling Point (or the Dry Point) and the Initial Boiling Point as measured by ASTM D-86.
  • the preferred boiling range will depend upon the use to which the fluid is to be put however, preferred fluids have boiling points in the following ranges:
  • a fluid having the desired boiling range may be obtained by appropriate fractional distillation of the hydrocracked vacuum gas oil.
  • the feedstocks used to produce the aliphatic hydrocarbon fluids have lower sulphur content (1 to 15 ppm by weight as opposed to 100 to 2000 ppm by weight in conventional fluid manufacture).
  • the feedstocks have a lower aromatic content (3 to 30 wt % as opposed to the 15 to 40 wt % in conventional fluid manufacture).
  • the lower sulphur content can avoid or reduce the need to install deep hydrodesulphurisation units and also results in less deactivation of the hydrogenation catalyst when hydrogenation is used to produce dearomatised grades.
  • the lower aromatic content also diminishes the hydrogenation severity required when producing dearomatised grades.
  • the non-dearomatised fluids also have a lower normal paraffin content (3 to 10 wt % as opposed to 15 to 20 wt % in conventional fluid manufacture) and a higher naphthenic content (45 to 75 wt % as opposed to 20 to 40 wt % in conventional fluid manufacture). These products have less odour, improved low temperature properties such as a lower freezing point and pour point and in some applications an improved solvency power.
  • the dearomatised fluids also have a higher naphthenic content (70 to 85 wt % as opposed to 50 to 60 wt %) and have improved low temperature properties and improved solvency power.
  • the fluids of the present invention are particularly useful as solvents for printing inks where the high polycyclic naphthenic content results in improved solvency for the ink resins.
  • the fluids are also useful in applications where they are subject to low temperatures, such as drilling fluids, since the low paraffinic content lowers their freezing temperature.
  • the fluids are useful as extender oils or softeners in silicone sealant compositions.
  • the fluids have the general benefit that their higher Initial Boiling Point means they are less volatile producing less undesirable volatile organic compounds and furthermore less fluid is lost due to evaporation.
  • Silicone sealants are organopolysiloxane based compositions hardenable at temperatures below 50°C in the presence of water which may be derived from humid air.

These generally include viscosity's of less than 4.0 cSt at 40°C, flash point of 100°C or greater and, for cold weather applications, pour points of -40°C or lower. These properties have typically been only attainable through the use of expensive synthetic fluids such as hydrogenated polyalpha olefins, as well as unsaturated internal olefins and linear alpha-olefins and esters. These properties are provided by some fluids of the present invention, the products having a boiling range in the range 235°C to 300°C (ASTM D-86) being preferred.

Further they have low pour points compared to other products made from vacuum gas oil feeds. Their viscosity does not increase rapidly with decreasing temperature and therefore they disperse more rapidly in the cold water conditions found in deep sea environments and northern climates. Therefore drilling fluids based on the present invention typically do not need to be stored in heated areas, even in cold weather climates.

  • the chemical composition is measured by the methods described previously, the aromatics being determined by liquid chromatography and the carbon number distribution by GC assuming that, for example, all products between the mid point between the nC13 and nC14 peaks and the nC14 and nC14 peaks are C14 material.
  • the hydrocracked diesel was fractionated to produce different cuts being 0 to 40 vol %, 40 vol % to 75 vol %, 40 vol % to 95 vol % and 50
  • Treat Gas Ratio 200 normal cubic metre of hydrogen gas per litre of liquid feed.
  • the HHD 0-40 is suitable for use as drilling fluid.
  • Example 2 illustrates the use of the fluids of the invention as silicone extenders for an acetoxy silicone sealant, sold by Bayer under the tradename Silopren, JurWWB 14057.
  • HHD 40-75, HHD 40-95 and HHD 50-95 refer to the 40-75% cut, the 40-95% cut and the 50-95% cut respectively.
  • the compatibility of the products with the silicone sealant were evaluated in formulations containing 25-30-35-40 wt % of the extender.
  • the evaluation is performed manually, using a polyethylene bag. First the silicone sealant is placed in the bag' and then the extender is added; the two components are kneaded manually until a homogeneous mixture is obtained. A small tip of the polyethylene bag was then cut away and about 20 grams of the mixture was pushed out of the bag onto a polyethylene sheet. A second polyethylene sheet was then applied on top of the heap of the mixture. A glass plate is placed on top of the second sheet and a force is applied so the heap is pushed flat to a thickness of (2mm).
  • the disks are exposed to ultra violet light (using an ultra violet lamp) for a period of 8 weeks.
  • the disk is divided in two equal portions. One half is exposed to ultra violet light, and the other half is covered with aluminium foil and a glass plate, blocking the ultra violet light. After 2,4 and 8 weeks, the disks are inspected visually and the effect of the ultra violet light is compared to the non-exposed half.
  • Three metal rings are prepared for each property to be tested.
  • Each unfilled ring is weighed in air (mass ml) for the volume test, also in a test liquid (mass m2).
  • the test liquid consists of 300 ml demineralised water containing 2 ml liquid soap (wetting agent).
  • the rings are then filled with the sealant to be tested, care being taken that no air bubbles are formed and that the sealant is pressed to the inner surface of the metal ring.
  • the sealant should be trimmed so that it is flat with the upper ring of the metal rings.
  • Each filled ring is then weighed in air (mass m3) and in the test liquid (mass m4).
  • test specimens After preparation and weighing the test specimens are suspended and stored under the following conditions: a. 28 days at (23 ⁇ 2)°C and (50 ⁇ 5)% relative humidity. b. 7 days at (70 ⁇ 2)°C in a ventilated oven. c. 1 day at (23 ⁇ 2)°C and (50 ⁇ 5)% relative humidity.

Abstract

Hydrocarbures liquides dont le point d'ébullition ASTM D-86 est situé dans une plage de 235 °C à 400 °C et dont la teneur en naphténe est supérieure à 60 % et contient des matériaux polycycliques. Ces hydrocarbures liquides possèdent, de préférence, une teneur aromatique inférieure à 2 % et un point d'aniline inférieur à 100 °C. Ils sont particulièrement utiles sous forme de solvants pour des encres d'imprimerie, des liquides de forage, des liquides d'usinage de métaux, et en tant qu'extenseurs de silicone.
